Hi I've installed and reinstall xampp few times now but I cannot get access to phpmyadmin I get the following error#1045 - Access denied for user 'root'@'localhost' (using password: YES)

The only thing I've changed was the appache port to use port 82 I can run php but not adminhttp://localhost:82/phpmyadmin/#1045 - Access denied for user 'root'@'localhost' (using password: YES)

I've never set up a password I am not sure if the previous person that was using this computer as set up username and password but is there a way to reset, delete add new password so I can gain access to phpmyadmin.
